Append current Date to Log file with Log4Net

Question

All I want to do is append the current date and time to my log file, say:

"export_(Wed_Feb_21_2009_at_1_36_41PM)"

Here is my current config from my app.config

<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
    <file value="c:\export.txt" />
    <appendToFile value="true" />
    <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
    <rollingStyle value="Size" />
    <maxSizeRollBackups value="10" />
    <layout type="log4net.Layout.PatternLayout">
        <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] - %message %stackTrace%newline" />
    </layout>
</appender>

Is appending the date to my log file possible, or is it one of those things I need to do in code and not config?

Answer 1

To produce file name like:

log_2013-12-19.txt

make changes

<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
    <param name="File" value="log_"/>
    <param name="RollingStyle" value="Date"/>
    <param name="DatePattern" value="yyyy-MM-dd.\tx\t" />
    <param name="StaticLogFileName" value="false"/>
</appender>

Please observe param "DatePattern" where .\tx\t makes the file name extension .txt. If you provide .txt instead of .\tx\t, then this would save file name with extension .PxP if the time is PM or .AxA in case of AM. so I used \t to enforce to write character instead of pattern. Time may also be added and what ever time pattern needed.

So, this may be really what Philipp M wanted.
